Android and Google Custom Search API

Question

I'm trying find images with help google custom search api.

Everytime i'm getting error 403. What i'm doing incorrect?

I registered project in google developer console, turned on Custom Search API and created Key for Android applications.

I have api-key and cx id

Code for getting search results:

String key = "AIzaSyBixxZ28popSAyP0YdlzvnWFECXktLQR4w";
String cx = "009034774129468977321:wl08kmocg3m";
String qry = "spring";// search key word

try {
    HttpRequestInitializer httpRequestInitializer = new HttpRequestInitializer() {
        @Override
        public void initialize(HttpRequest request) throws IOException {
        }
    };

    JsonFactory jsonFactory = new JacksonFactory();
    HttpTransport httpTransport = new NetHttpTransport();

    Customsearch customsearch = new Customsearch.Builder(httpTransport, jsonFactory, httpRequestInitializer)
            .setApplicationName("CTTProject")
            .build();

    Customsearch.Cse.List list = customsearch.cse().list(qry);
    list.setKey(key);
    list.setCx(cx);
    Search results = list.execute();
    List<Result> items = results.getItems();

    for (Result item : items) {
        Log.d("Response", item.toString());
    }

} catch (IOException e) {
    e.printStackTrace();
}

everytime I'm getting result:

Answer 1

Although a very late answer but it maybe helpful for others. This problem happens because you are using the wrong key in making the request.

Instead of "Android Key" you have to create a "Browser Key" and use it for making the request.You can create Browser Key from Credentials section in the Google API console.

Example

https://www.googleapis.com/customsearch/v1?q=a&key={BROWSER__KEY}&cx={SEARCH_ENGINE_KEY}
